Mounting the Siren
The Model SST3-MV can be attached to any relatively flat
surface or to a variety of electrical wall boxes. A four-position
plug is supplied for electrical connection. In addition, two #8-
32 x 3-1/4 inch slotted machine-screws are included to attach
the unit to a four-inch square electrical box. After the mounting
method and location have been selected, follow the procedure in
the appropriate section below. For clarity, The speaker portion of
SST3-MV is not shown in the illustrations.
The speaker and its base assembly provides three degrees of
freedom, allowing the siren to be oriented for any coverage pattern
desired. The angle is adjusted with hand-tightened nuts that require
minimal torque to maintain the position of the siren.
